UNITED STATES PATENT OFFICE.

Application filed January 7, 1925. Serial No. 1,088.

To all whom it may concern:

Be it known that I, Tnoms G. Rrormnns, a citizen of the United States,and a resident of Barberton, county of Summit, State of Ohio, haveinvented certain new and useful Im rovements in Laminated Articles, ofwh1ch the following is a specification.

The use of X-ray machines is attended with injurious eflects upon theoperators, or those whose work requires attendance on or near themachines, the rays being dangerous to human organisms, as is well knownto those familiar with their use.

It is the purpose of the present invention to provide a material which,when worn, will serve to protect the operators from the injuriouseifects of the rays, and for this purpose I ro to use metallic lead, oneof the rogerili of which is that it intercepts the iI-rays. Shouldsubstances other than metallic lead be found to have similar propcities,it is intended to cover the use of such substances as well.

In the drawings herein, there is shown one form of the invention, andfor the purpose of illustration I have shown and described themanufacture of a glove, but it will be understood that the invention maybe practised in the manufacture of other articles of wearing apparel,such as aprons, coats, or the like. Other changes and modifications maybe made in the practising of the invention.' The method of manufacturingthe article is covered by the copending divisional application hereof,Serial No. 73156, filed December 4, 1925.

In the drawing:

Figure 1 shows a glove upon a form and constructed in accordance withthe invention; and

Figure 2 is a fragmentary cross-section of the finished product upon. amagnified scale, showing the construction of the several layers whichconstitute the laminated structure.

In describin the invention I have shown a seamle$ rubier glove which ismanufactured upon a form such as shown at 1. This is made of glass orporcelain and is dipped in a solution of rubber a suflicient number oftimes to build up a. glove 2 of the proper thickness. After eachdipping, and while the layers of rubber are in a tacky condition, a finecoating of powdered metallic lead is tion.

erty of protecting the operator from the injurious effects of the re. s,and so far known to me 1s the first practical construction for the usesand purposes set forth. The lead is impermeable to X-rays and thearticles are flexible and can be used in the same manner as the ordinaryrubber glove.

In constructing other articles of wearing apparel, the method of formingthe layers of rubber may be varied as dictated by the character of thearticle to be manufactured and I do not intend to be limited to theparticular method or to the specific articles herein shown anddescribed.

What is claimed is:

1. A flexible, protective coverin for use by X-ray operators comprisingayers of rubber and layers of metallic lead adhesively secured to thelayers of rubber and vulcaniz ed therewith.

2. 'A flexible, protective coverin by X-ray operators comprising a 51 ofrubber and a thin layer of powdered lead permanently secured t ereto byvulcanizafor use 3. A flexible, protective covering for use by X-rayoperators, said covering containing powdered lead in a layer over theextent of the covering between layers of rubber.

. 4. A oneiece, flexible, protective covering for use y X-ray operatorscomprising a plurality of layers, one of said layers containing asubstance impermeable to X-rays, said substance bein distributed evenlythroughout the covering.

5. A garment com rising successive layers of rubber and pow ered lead insuflicient volume to render the garment impermeable to X-rays.

6. A garment comprising thin layers of rubber and thin layers of amaterial impermeable to X-rays.

in layer 7. A laminated sheet comprising thin layers of rubber and thinlayers ef powdered lead in suflicient volume to render the sheetimgermeable to X-rays.

8 A laminated flexible sheet eomprising thin layers of rubber and thinlayers, of a I substance impermeable X-rays adhesively secured to thelayers of rubber and vulcanized thereto.

9. A laminated flexible structure comprising a. layer of rubber andahge'r of a substance imfmrmeable to X-rays, e said layers canized beingvu er.
